MAGAZINE FIRE-Aam.

SPECIFICATION forming part of Letters Patent No. 366,563, dated July l2,1887.

Application filed August 4, 1855.

To all whom it may concern.-

Be it known that I, ANDREW BURcEss, a citizen of the United States,residing at Owego, inthe county of Tioga and State of New York, haveinvented certain new and useful Improvements in Magazine Fire-Arms, ofwhich the following is aspecication,referencelbeing had therein to theaccompanying drawings.

My invention relates to double or single magazine or breech-loadingdre-arms, andhas for its object improvements in their generalefficiency; and it consists of new arrangements in the operation andlocking devices and construction of parts, hereinafter more fully setforth.

Figure lis a longitudinal sectional elevation of the frame and breechmechanism of this gun in closed position, showing a slidingguard-handle, a carrier, and the device for locking the operating rodand handle, and connection for discharging one barrel by pulling off theother, a forward sliding handle being indicated in broken lines. Fig. 2is a similar View, with some modifications, in open position, toespecially show the sliding guard, many other part-s being omitted. Fig.3 shows the double bolt, top View, butpartly cut away to show relationof the carrier-operating levers to the carrier. Fig. 4 is a bottom viewof the bolt, with the lifting-levers modified so that the points forengaging the carrier are forward of their pivot. Fig. 5 isacross sectionlooking rearward from the face of the bolt, the central part of the boltbeing broken away. Fig. 6 is a perspective showing the twin hammer andmeans of releasing one by the other.

This arm contains many features specially adapted for double-barreledmagazine-guns, in which a single reciprocating bolt closes the breech ofboth barrels. Many of the parts are referred to in the followingdescription in thesingular number, where they can be single forasingle-barreled gun and duplicate for a double gun.

A is the fra1ne5B, the bolt; B', the lockingbrace; C, the carrier; c andc', projections 0f carrier; D, the dog-lever to lock a sliding handle;d, aprojeetion on the hammer to disengage the dog from its notch b; E E,the eX- tractors; c and e', the lifting-levers, j', a lifting-piece todisengage the locking-dog; G, the sliding guard; H, the hammer; L, thelever to Serial No. 173,569. (No model.)-

operatethe locking-brace; M, a magazine; P, the pivot of lifting-levers;It, the operatingrod, which connects a sliding handle to the breechmechanism. S is a sliding handle nnder the barrel. hand sear, and t thelefthand sear. Ik is a piece or strap to connect the left-hand scar andright-hand hammer; h, a slot or groove in the hammer to receive the pint ofthe connecting-strap t?, and h is a thumb-piece on strap t2. Thisarm is provided with a reciprocating bolt, and is locked by a vibratingbrace pivoted therein and which bears upward against ashoulder in theframe to lock the bolt, and is turneddownward into the body ofthe boltto unlock it, as I have shown in former applications.

The brace B is operated by asliding handle which moves a rod, as R, toengage the downward-extending arm L of the lever L to vibrate said leveron its axis or fulcrum, which is here shown as a pivot in the bolt, sothat the rearward-extending horizontal arm of said lever s vibrateddownward'by the backward movement of the operating-rod and upward by theforward movement of said rod; andthe horizontal arm ofthe lever L beingconnected to the brace, as by a pin, l), and slot, the brace is therebymade to partake of the downward and upward movement of said arm ofthelever to unlock and lock the bolt in the frame. Another pin, asp', isfixed in the frame, and the forward arrn of the lever L has a camprojection or incline to engage and bear against said pin as the breechis being opened, and thereby cam back the bolt as the brace is beingnniocked by the lever, the locking-faces of the brace and shoulder inthe frame being cut eccentric with the pivot of the brace to allow somebackward movement of the bolt while being unlocked.

I show substantially the above arrangement of lever L in my application,No. 171,940, of July 18, 1885, but do not claim it therein. VI showthesliding guard connected to the rod R and serving as a handle tooperate it; but the operating-rod R may be moved by a forwardslidinghandle, as S, either alone or in combination with a rearward handle, oreach may be connected to a locking-brace (by a separate rod) when twobraces are used in a double bolt, like that shown in Fig. 4; but Iherein T is the trigger, t the right-- make no claim to the forwardhandle, but

. broadly do claim the means shown, and herein the operating-rod R, oraconnection therewith, in Yposition to be enga-ged by the dog when saidrod is in its forward position t'o lock the breech, as seen in brokenlines in Fig. .1; but when the hammer falls te tire the gun itsprojection d engages the free arm of the doglever to turn its forwardend upward out of locking engagement with shoulder b, as shown in fulllines in same figure, so that the rod It is thereby made free to movebackward to open the breech. 4

I here show the dog D as operated by a`vi brating hammer to unlock theoperating-rod or sliding handle; but it may be operated in like mannerby connection from the iiring-pin, (especially when the firing-pinserves as a hammer by being provided with a spring,) or it may beoperated by the recoil of the bolt or gun; but these specific detailswill be claimed in other eases.

It is obvious that the locking-dog will operate in the same manner,whether a sliding handle and ,operating-rod are applied to areciprocating or vibrating breeclrpicce.

In Fig. 1 it will be seen that the mortise connecting rod R to thebreech mechanism is elongated forward, so that the said trod will haveto move back a little before operating on the breech. This lost motion77allows an instant of time to pass between the unlocking of the rod andoperating-handle by the striking of the hammer (if the operator shouldbe pulling back on the handle and rod at the time of firing) to allowtime for the discharge to take 1 place before the breech is started tounlock,

and so the slight hang-tire possible may not iind the bolt entirelyunlocked.

A swinging-foil or iingerpiece, asf, is hung inside the loop oftheguardv in position to be engaged at will' by the finger that pulls thetrigger, so that the forward end of said foil f may be thus swung up tostrike the end d of dog D, to force it up out of engagement with itsshoulder b to unlock it, or to prevent its locking the handle, whendesired, as when the trigger is kept under constant pressure in veryrapid firing. It is obvious that this device, operated,as described,from the outside of the gun, may be used alone in connection with thedog D or in combination with the automatic releasing projection d on thehammer.

Vhen I arrange the mechanism, substantially as shown and described, in-a doublebarreled magazine-gun,with one or both hammers hung to vibrateup and forward to fire the gun, I attach a strap, as t2, Fig. 1, to thescar rearward of its pivot, as the left scar, t', and said strap extendsupward tovengage the inside of right-hand hammer in its slet h by a pin,as t, so the hammer may be cocked, as

in Fig. 2, (moving its slot h freely over the pin th) but when thehammer falls, as in Fig. l, the abutment at the lower` termination ofthe slot 7L engages the pin t, vand thereby lifts the strap and end ofthe sear to fire the left barrel immediately after the right shall betired by pulling the trigger.

XVhen the use of strap tl is not required, it may be turned to the leftand back to disengage its pin t from the slot h, as shown in dottedlines, Figs. l and 6.

I herein claim only the special double-firing arrangement shown, as itdiffers from that shown and claimed, broadly, in my application No.145,558, filed October 15, 1884;.

W'hen this gun is constructed with two barrels which are closed by asingle bolt, I arrange that bolt with lifting-levers, as c e, Fig. b.The forward ends ot' said levers have thuiinb-pieces c7' and e, by whichto swing them laterally, so that their forward wedge-shaped ends c andef may be swung under thespring extraetors to raise them out ofoperative position,while at the same time and by the same means the rearends of said levers are swung into or out of position for engaging thecarrier. By this arrangement, by pressing the ends cl and c3 of theliftipglevers together theirwedge projections are withdrawn from underthe extractors, so that they may fall to engage the cartridges, and therear ends turn by the same movementoutward to the line oftheproj ectionsC C of the carriers, by which thelevers,where Ithey project below thebolt, engage said carriers to operate them, so that the one movementofpressing the forward ends of levers e ICO e together throws the boltfrom the inoperative condition of Fig. 3 into operative relation withboth barrels and magazines, and a reverse movement of the levers raisesthe extractors out of operation and turns their projections out of linefor engaging the carriergor each lever may be operated alone, as shownin the modification, Fig. 4, so that one barrel alone will be operated.

It will be seen that the levers c e, Fig. 4, are substantially the sameas those of Fig. 3, except that the projection behind the pivot isomitted, and the engaging-pointsayre placed on the forward instead oftherear part. The operation onboth extractors and carriers is precisely thesame in both eases.

I claiml. In a breech-loading firearm, a reciprocating bolt and a bracepivoted therein to lock the bolt against a bearing in the top of theframe, in combination with a lever pivoted in the bolt and havingengagement with the brace, and a connection below the bolt with adownwardextending arm of said lever, and a sliding handle to operate thebreech, substantially as described.

2. In a breech-loading fire-arm, a reciprocating bolt and a bracepivoted therein to lock the bolt against a bearing in the top of theframe, in combination with a lever pivoted in the bolt and havingengagement with the lIO IIS

brace, and a connection below the bolt with a downward-extending arm ofsaid lever, and a sliding handle to operate the breech, and an t asdescribed.

part of the operating mechanism to release the dog from its engagement,in combination wlth a projecting foil-piece in position t-o be engagedby the operator to release the dog aty will, substantially as described.

6. In a breech-loading lire-arm, a sliding handle which moves thebreech-piece, a locking-catch for said handle, and an abutment on amoving part ofthe operating mechanism by which said catch is disengagedand the handle released in firing the gun, all in combination,substantially as stated.

7. In a double magazine-gun, a sear to hold one lock in a cockedposition, and a strap pivoted to said Sear and attached to the vibratinghammer ofthe other lock of t-he gun bya slotandpin connection to permitthe cooking of the hammer, all in combination, so that the firingmovement of one hammer releases the sear of the other lock,substantially as set forth.

S. I`n a breech-loading fire arm having two hammers, the combination,with the sear of one hammer, of a strap pivoted to said sear andconnected to the other hammer by aslot- .andpin connection, and aconnecting-piece extending outside the frame of the gun for disengagingsaid strap, substantially as described.

9. In a double-barreled magazine gun, a single movable breech-piece toclose both barrels, a separate extractor on said breech-piece for eachbarrel, and a shifting-piece by which one of the extractora may bethrown out of operation while the other remains in operative position,all in combination, substantially as described.

10. In a double-barreled magazine-gun, a reciprocating bolt,two-extractora carried by said bolt, and two shifting-levers arranged inthe'gun in positioh to engage said extractors, substantially asdescribed, whereby by the shifting of the levers either or bothextractors may b`e thrown out of operation, all in combination, as setforth.

11. In a`double-barreled magazinegun, the combination, with the barrels,of a single reciprocating bolt, two carriers hung in the y frame, arid ashifting-piece in position to cn gage or disengage one carrier and thusthrow it into or leave it out of operation.`

A 12. The combination, in a double magazinegun, of a reciprocating bolt,two extractors carried thereby, two cartridge-feeders, and ashifting-piece which may be thrown in'to engagement with one extractorand one feeder to throw said parts out of operation, substantially asdescribed.

13. In a magazinegun, the combination, with a reciprocating bolt, anextractor thereon, and a cartridge-carrier, of a shifting-piece on thebolt, which may be placed in position, substantially as described, torender both the extractor and carrier operative or both inoperative, asand for the purpose stated.

14. In a breech-loading gun, the combination of a sliding handle whichoperates the breech, a catch which locks said handle, and a movingabutment, substantially as dcscribed, in position to disengage thecatch, with a breech-piece and aloose`connection from the handle to thebreech-piece, whereby a slight movement of the handle is permittedbefore the breech is started, substantially as described. 1

15. In a double gun, two hammers each having a holding-scar, atrigger inconnection with one Sear, by which to release it from its hammer, and aconnection from the hammer thus released to the sear of the otherhammer, whereby the second hammer is released by the striking of therst, .all in combination, substantially as described.

z In testimony whereof I herewith aix my signature in presence of twowitnesses.
